I have an LMM with straight pipe from downpipe back, 3 inch downpipe, bigger up pipe passenger side, fual rail plug, resonator delete, pcv reroute, and then heavy town tune EFI Live. I am doing PPE Air Box Mod...is there anything else I can do for cheap at home to make my truck perform better. I have no complaints at all about performance but you know when your a gearhead it is never fast enough. Also not just performance mods but things that are better for the engine like I did the PCV reroute is there anything else I can do to gain performance, clean up engine bay or do anything that helps my motor?
